Its not chain length that dictates if a tensioner is required but frame design and clearance. A bike equipped with with horizontal drop outs and chain stays wide enough for chain clearance does not require a tensioner. Many have successfully gone that route. Consider using the tensioner on the pedal chain and maintaining engine chain tension by either shimming the engine at the rear mount or, if you have them, use the drop out adjustment and half links. The Jag is a great platform for a motorized bicycle; I have two of them and their only shortcoming is the close coupled seat. A lay-back seat post greatly improves the comfort of the ride.
